Showcased here is an unpainted Red Tornado first shot. As the pictures convey, most of the figure is cast in red injection molded plastic, while the crotch section is shot in a milky white plastic. First shots, sometimes referred to as test shots, are used to test the steel molds prior to mass production. The color of the injection molded plastic was irrelevant since the figure served only test purposes.
This particular first shot lacks copyright dates and information on the leg, but does exhibit footholes.
Above is a comparison photo showing the first shot on the left and the fully painted production figure on the right. First shots which visually differ from their production counterparts by the presence of non-production color areas, like this Red Tornado, are interesting artifacts of the production process and are more highly coveted by collectors than those which simply lack copyright information.
